- Acquires four NAMUR encoder signals in accordance with EN 60947-5-6
- Detects open-circuit and short-circuit conditions for each input channel
- Allows every input to operate as an 8-bit event counter
X20DI4760 is a B&R namur digital input and counter module designed for X20 System I/O stations.
It integrates the documented I/O channels, electrical behavior, diagnostics, and model-specific functions into a compact X20 station slice.
Before installation or replacement, verify the complete material number, sink or source topology, terminal and bus modules, field supply, wiring, software configuration, and installed-system requirements.
Availability, condition, price, and shipping time for X20DI4760 are confirmed during quotation.

- Open-circuit and short-circuit conditions are detected on each input channel
- Channel faults are indicated through LEDs and software status
- Normal switches can also be evaluated in addition to NAMUR encoders
- All four inputs can operate as cyclic 8-bit event counters
- Each counter evaluates the positive edge of the input signal
- Maximum count frequency decreases as the number of simultaneously active inputs increases
- ATEX Zone 2 approval: II 3G Ex nA nC IIA T5 Gc, IP20, subject to the X20 user's manual requirements
- cCSAus certification covers Class I, Division 2, Groups A, B, C, and D hazardous locations with a T5 temperature code
- Documented marine approvals include DNV, CCS, Lloyd's Register, Korean Register, ABS, and Bureau Veritas
